TO ALL WHOM IT MAY GONCERN: l

Be it known that I, GEORGE W. CHIPAIAmof Bostenfin the county ofSuifolk, and State of Massachusetts, have invented an Improvement inCarpet-Lining; and I do' herebyl declare that the following, taken inconnection with the drawings which accompany and form part of thisspecification, is a description of my invention suicient to enable thoseskilled in the nrt to practise it.

UnitedStates Letters Patent, No. 14,585, granted to J. It. Harrington,and now owned by me, relate to the mannfacture of a-carpet-lining,consistingr of acontnuous sheet or layer of softloose, iihrous material,surfaced by a sheet or sheets of stout paper, the batting being kept inplace, relatively to thesurface of the paper, by cement or otherwise. Y

The moans for so uniting the paper and wedding-have been to cement 'theentire inncusurface. of the paper to the wadding, to press the sheetstogether, to cement together the adjacent edges of' the paper sheets, orto stitch the sheets together, each of these means beingpraeticnble,though there are some objections to the use 4lofV either.

rIn my present invention I use cementltious matter to confine the sheetstogether, but instead of's'preading it over the whole surface of'thepaper, I apply it in spots, or in parallel 1ines, whereby I retainthegeneral 4elasticity of the wadding, or prevent the paper and waddingfrom matting together, as they incline to do in covering the paper withcement, and counteract the tendency of the paper to tear at thelines`ot` connection,

as'it inclines te do in sewed-lini'n'gs.

My invention consists in a carpet-lining, in which the sheets of paperand of soft iibrous lling are secured together, or from relative lateraldisplacement, by spots or lines of cement, distributed over the surfacesin contact, at such intervals of space as shall permit the liningtopreserve the general fulness or elasticity desirable .ina carpet-lining.

The -drawing represents apiece-of carpet-lining embodying myimprovement.

a and b denote the two sheetsot paper; e, the sott-wedding or battingenclosed between them.

d d denote spots of cement, or spots opposite to which the cement isapplied, 'the cement being dropped pr applied, by'a suitable brush, totbe'inner surface of the paper, at regular intervals, by mechanismconnected with and forming part of the linii'ig-'makii'ig machine, thecement being applied to each sheet ofpaper just before the paper andwedding come intocont'aet. i

v Instead of using drops or spots of' cement in this manner, thc cementmaybe applied in short lines, as shown at e, or in continuous lines, asshown at f. v Y

I claim a carpet-lining, the wadding and paper sheets ofwhich areconfined together by the lines or spots of cement, substantially assetforth.
